"the user-agent switch involves adding a Safari identifier" Well, the default user agent string for Chrome already has a Safari identifier in it, but I don't think Safari user agents have a Chrome identifier. The change being made in the post doesn't add a Safari identifier, because there was one there already, but it does change the OS string to Windows. So I think the explanation in the post is probably right.
